PRODUCTEMIStream for 2-Layer Boards [Option]
Learn more about EMIStream for 2-Layer Boards.
What Is EMIStream for 2-Layer Boards?
It features EMI checks tailored to the characteristics of 2-layer boards, including a selection of rule checks that assume no internal plane layers and additional checks specifically suited to 2-layer boards. It identifies component placements and routing that may cause EMI issues and suggests countermeasures.
- * This is an optional feature. It is included as standard in the EMIStream Expert Edition. It is also available as a standalone feature.

Return Path Check to the Ground Pin [Return Path]
2-Layer Board EMI Check Results (Return Path)
Checks the path taken by the signal return current until it returns to the LSI ground pin.
Even when the ground trace runs parallel to the signal trace, radiated noise can increase if the return path from the point where the parallel routing ends to the ground pin is too long.
GV Loop Path Check [Decoupling Capacitor]
2-Layer Board EMI Check Results (Decoupling Capacitor)
Checks the current loop between the LSI and the decoupling capacitor.
Verifies that the current loop path, including the ground side, is as short as possible.
- * The capacitor with the shortest total GV loop distance is selected for checking.
